BlackBerry data plan is the mobile data service specifically for BlackBerrys. Generally you need it to use mobile data on a BlackBerry, at least for BlackBerry apps and most third party apps.

The reason dc asked if you have a BlackBerry data plan is because many carriers do not allow wifi on a BlackBerry unless you have the plan on your line. This is the first question, do you have the plan on your line and is it active on the handset you are using? If so, then you can look at other possibilities. If you don't have the plan, then that is the most likely answer to your problem.Posted via BlackBerryForums.com Mobile
